State Park · Hawaii
Kauai's inaccessible cathedral coastline of 3,000-foot fluted sea cliffs, reachable only by the 11-mile Kalalau Trail, by kayak in summer, or by boat tour, demanding a permit for anyone going beyond the first valley.
Field briefing
Nāpali Coast State Wilderness Park starts with access, not mileage.
Before you go
The 11-mile Kalalau Trail is the only land route into the wilderness, and it requires a permit for anyone pushing past the first valley at Hanakāpīʻai. Permits are released 90 days in advance through the Explore Outdoor Hawaiʻi system at camping.ehawaii.gov; non-resident fees are $35 per person per night plus a booking fee. Plan the permit booking like a competition: midnight Hawaii time exactly 90 days out. Day hikers can do the first two miles to Hanakāpīʻai without a permit but must turn around there. A separate parking reservation at Keʻe Beach through gohaena.com is required before you can secure a Kalalau permit.
Weather, crowds, and what the season changes about the trip.
North shore swells begin to ease by late April. Trail conditions improve through May, when hiking becomes more reliable and kayak landings reopen.
Pack Rain gear is still needed through April, trekking poles for the muddy switchbacks, and permits secured 90 days in advance.
The prime window: calmer seas, drier trail, trade winds keeping temperatures in the mid-80s F. Kayak-camping access to Kalalau Beach is possible June through September.
Pack Sun protection for the exposed ridge sections, river shoes for the multiple stream crossings, and a permit locked in 90 days out.
Transition season with increasing rain and occasional north swells. October can still be hike-able but conditions deteriorate through November.
Pack Full rain gear, trekking poles for slick clay sections, and close attention to the permit system and trail conditions from Hawaii DLNR.
20F
Dangerous. North swells can exceed 20 feet, washing across the Kalalau Trail coastal sections and into the campsites. The park does not close but serious injury and fatalities have occurred.
Pack Expert-only conditions in winter; research current Hawaii DLNR advisories, carry emergency gear, and have a bailout plan for any section that floods.
Kalalau Trail: Keʻe Beach to Hanakāpīʻai Beach
The first 2 miles of the Kalalau Trail, open to day hikers without a permit. It drops into the first valley and ends at a remote beach with waterfall access inland. Strenuous with significant elevation change and stream crossings.
Kalalau Trail: full traverse to Kalalau Beach
The full 11-mile permit-required trail past Hanakāpīʻai to the Hanakoa camping valley and finally Kalalau Beach at the base of the cliffs. A multi-day backpacking route rated among the most spectacular and demanding in the Pacific.
Kalalau Valley and Kalalau Beach camp
The terminus and overnight camp at the base of the Nāpali cliffs, with a 1.5-mile inland trail to a waterfall. Camping is limited and the permit waitlist is competitive; this is one of the most coveted backcountry campsites in the United States.
Sea kayak along the Nāpali coast (summer only)
From May through September, sea kayakers can paddle the full Nāpali coastline from Keʻe to Polihale, landing at Kalalau Beach with a valid camping permit. This requires a boat permit and experienced open-water kayak skills.
Put the access rule first: shuttle, parking, timed-entry, or reservation windows should decide the order of the day. For one day in Nāpali Coast State Wilderness Park, make Kalalau Trail: Keʻe Beach to Hanakāpīʻai Beach the non-negotiable, add Kalalau Trail: full traverse to Kalalau Beach only if the first stop runs clean, and keep Kalalau Valley and Kalalau Beach camp as the flexible finish.

Getting there
Fly in
The Kalalau Trail trailhead is at Keʻe Beach at the end of Highway 560 on Kauai's north shore, about 40 miles and 75 minutes from Lihue Airport.
Access note
Parking is extremely limited and requires a separate advance reservation through gohaena.com; do not attempt to arrive without a parking reservation.
Car strategy
The road to Keʻe is famously narrow and one-lane in sections.
Pair this with lodging: sleep where the park transfer is simple, especially if your route needs an early start.
You do not need a permit for the first 2 miles to Hanakāpīʻai Beach. A camping permit is required for anyone going beyond Hanakāpīʻai, even if you are only day hiking to mile 6 or beyond and not camping.
The full 11-mile trail is one of the most strenuous hikes in the United States. It involves significant elevation gain and loss, multiple stream crossings, narrow clifftop sections, and sections that wash out in heavy rain. The first two miles to Hanakāpīʻai are challenging but manageable for fit hikers.
May through September is the best window, when north shore swells are calmer, the trail is drier, and stream crossings are less dangerous. Winter brings powerful north swells, heavy rain, and hazardous conditions on the coastal trail sections.
Yes, from approximately May through September when sea conditions allow. Sea kayaking the coast requires experience, a boat permit, and a valid camping permit if you plan to land and camp at Kalalau Beach. Guided kayak tours also operate from Port Allen during the calm season.
